feign-eureka's Introduction

feign-eureka

Example of using feign with eureka

Assumes eureka (from spring-cloud-samples) is running on http://localhost:8761

building

mvnw package

hello server

run java -jar server/target/feign-eureka-hello-server-0.0.1-SNAPSHOT.jar

verify it is functioning at http://localhost:7111

You should see Hello World: HelloServer:myhostname:7111

hello client

run java -jar client/target/feign-eureka-hello-client-0.0.1-SNAPSHOT.jar

verify it is functioning at http://localhost:7211

You should see Hello World: HelloServer:myhostname:7111

hello client error

You may see an error while the eureka/loadbalancer caches warm up similar to the following:

Load balancer does not contain an instance for the service HelloServer

It should go away shortly.

See round robin load-balancing in action

run java -jar server/target/feign-eureka-hello-server-0.0.1-SNAPSHOT.jar --server.port=7112

Go back to http://localhost:7211 and you should see both ports 7111 and 7112 in the output after a minute or two as you keep refreshing.

Any suggestion?

Thanks

about service is shutting down

hi ryanjbaxter,
thanks for you help,i run this code normally.
but i found that hello-service is shutting down and not be removed from eureka server soon.
how can do it will be removed so fast?

org.springframework.cloud.openfeign.EnableFeignClients#defaultConfiguration. Is there a problem with its priority

version: 2.2.2.RELEASE
i want to use FeignConfiguration as global configuration, and specify the configuration FooConfiguration for the IAnotherClient separately. why can't Fooconfiguration coverage the FeignConfiguration?
Why use the following approach to customize global configuration over custom local configuration?

@EnableFeignClients(defaultConfiguration = FeignConfiguration.class)
public class OpenfeignConsumerExampleApplication {

@FeignClient(value = "OPENFEIGN-PROVIDER-EXAMPLE",
        fallback = AnotherFallback.class,
        contextId = "IAnotherClient",
        configuration = FooConfiguration.class)
public interface IAnotherClient {

i havethe eureka server http://127.0.0.1:8761,http://127.0.0.1:8762,http://127.0.0.1:8763,some service named app1,app2,,,appn,how can i get the service in appx, i can't use @FeignClient because the appx is uncertain,
the eureka server is configured in the application.yml

osx spring bootRun can't debug api-gateway for remote eureka service in docker container

eureka-server up some service in remote centos host .
osx
api-gateway config eureka-server url
./gradlew api-gateway:bootRun
when connect service from eureka-server, got connection refuse error.

Exception when shutting down feign client

When you stop application with Feign client (feign-eureka/client in our case) via actuator shutdown endpoint (POST http://localhost:7211/shutdown) it complains with the following exception:

"Could not autowire. No beans of 'HelloClient' type found" encountered in feign client example

Hi,
I have encountered an autowired issue when trying to use the feign-eureka example. Here is a piece of code where the error reported by IDEA:
@Autowired
HelloClient client;

Below is a snapshot:

When app start up, DynamicServerListLoadBalancer list of Servers is always null

I use feignclient with eureka， server A need to call service B use feign , when service A start up, the first call to service B is always fail.
I find that the loadbalancer has no server, and then "Using serverListUpdater PollingServerListUpdater", I think it is better to pollingserver list when Server A start up .

Issue while running Feign sample

While running the HelloClient in Cloud foundry , I am getting unknownhostexception. Need your help to resolve this issue.

Spring Feign client cannot lookup the service url using service name

I've taken the code from this repo, and tried to run with the Eureka server shared in the link here. But getting an error below. It seems the lookup of the server url from Eureka is failing. Is there anything I should be looking at? Eureka server, serverapp and client app are all running on the same machine.
